[Accession No. 147. Section 188. Actual Size, 15X7 mm.] ing from these origins they make their entrance into the cerebral peduncle and ultimately reach the pons. At this point they alter their direction from the vertical to the horizontal plane, thereafter pursuing a transverse course. Many of these fibers end in the pontile nuclei of the same side for a relay here. The relaying axons then undergo decussation across the midline and eventualh' enter the middle cerebellar peduncle (Mcp). Some pallio-.
